Navy Explosive Ordnance Disposal teams trace their history back to the first group of volunteers selected to work with the famed British UXO teams, following the initial German Blitzkrieg attacks in early 1940. In June 1941, these veterans returned to form the first class in what was originally named the Mine Recovery School. Officers and enlisted personnel entered the eleven-week school, qualifying as Mine Recovery Personnel/Second Class Divers.

Between June 1941 and October 1945, nineteen classes graduated and deployed throughout the Pacific and Mediterranean theaters. Divided into Mobile Explosive Investigative Units (MEIU) they were instrumental in the clearance of explosive hazards both on land and at sea. The conflict in Korea saw a return to action on various minesweepers ensuring the continual clearance of shipping hazards. Additionally, the now renamed Explosive Ordnance Disposal (EOD) Units took part in inland intelligence operations and interacted with ground-based units in Inchon, Wonson and throughout the United Nations Theater of operations.

Vietnam saw an increase in overall participation by EOD units. Units from EOD Mobile Unit ONE, Pearl Harbor, Hawaii deployed throughout the region. With an overall emphasis in sea and riverine mine clearance operations, these teams ensured the continued safety for shipping and maritime operations.

Since the close of the Vietnam conflict, the ever-changing world situation and increased operational tasking have prompted the expansion of EOD units in number, size and capabilities. Their impressive record in recent history includes the Persian Gulf War where EOD Technicians cleared in excess of 500 sea mines. EOD was the critical element in eliminating unexploded ordnance from the USS STARK after two Exocet anti-ship missiles fired from an Iraqi aircraft hit her. EOD developed render safe procedures on-site to prevent a catastrophe. During joint operations in Somalia, Haiti, Bosnia, and Kosovo, EOD provided safety and operational continuity by eliminating booby traps, weapons caches, and performing mine clearance operations. EOD units are presently serving in Afghanistan and Iraq where they are supporting the global war against terrorism, destroying tons of post war ordnance and reducing the threat imposed by Improvised Explosive Devices (IED) that have plagued both countries. Forward deployed and fully integrated within the various special operations and warfare units within the Navy and Marine Corps, the present day EOD technician has changed greatly from that first Mine Recovery class of 1941. But one thing that has never changed is the level of professionalism and dedication that has been the cornerstone of the program.
